IMPROVEMENT IN SASH-BALANCES.

Specification forming part of Letters Patent No- 192,680, dated July 3,1877 application filed June 4, 1877.

To all whom it may concern Be it known that I, WILLIAM CASHNER, ofPleasant Hill, in the county of Cass and State of Missouri, haveinvented a new and 1111- proved Sash-Balance, of which the following isa specification:

In the accompanying drawing, Figure 1 represents a vertical section of awindow with sashes and my improved sash-balance; Fig. 2, a detailhorizontal section on line wwof the sash, and Figs. 3 and 4 are a detailside view and section of the spring balance pulleys.

Similar letters of reference indicate corresponding parts.

The invention is intended to furnish an imprcved sash-balancing devicewhich has the advantage of being confined into small space and hung at amore convenient place than the boxes, dispensing entirely with theboxes, weights, cords, and pulleys, and being also less expensive andeasily adjusted. for the weight of the sash than the same.

The invention consists of the sashes of a window hung by cords to doublespring-pulleys, turning in opposite directions, and being retained inany position by sliding springbolts and pins acting on recesses of thesashes, as hereinafter more fully described and claimed.

In the drawing, A represents the windowcasing, and B the sashes, whichare hung, by cords O, to double spring-pulleys B, whose shafts aresupported at one end in socketbearings of the windowcasings, and at theother ends by pendent brackets 11, screwed to the top part of thecasing.

The balancecords G are wound up in opposite directions on the doublepulleys B, one pulley being larger than the other, and the larger oneprovided at the interior with a coiled band-spring, b, of which one endis at-' tached to the casing, the other to the shaft of the pulley. Thespring is thereby called into action by either sash and wound up onlowering them, so as to assist in raising them.

A sliding spring-bolt, D, with cross-pin d, bears into recesses e ofeach sash, and secures the sash at different heights, by looking intothe same. By pressing back the spring-bolt the sash is easily raised inconnection with thebalance-pulleys. Two balance-pulleys,one at eachcorner of the window-casing, are sufficient for ordinary sashes, whilefor heavy sashes a third pulley may be arranged in the center of thecasing. The separating revolving sections of each double pulley B areoperated by the same spring, as they are turned in opposite directionsby the sash cords. Thus a compact and cheap sash balance is produced;or, instead of a third pulley, as stated above, a set of springs ofheavier gage may be used. I r a Having thus described my invention, 1

claim as new and desire to secure by Letters Patent- 1. As animprovement in sash-balancing devices, the combination of the sashes B,cords O, and double spring-pulleys B, said cords winding in oppositedirections on the separately-turnin g and spring-acted sections of thedouble pulleys, substantially in the manner and forthe purpose setforth. 1

2. The combination of the spring-balanced sash, having side recesses,with the sliding and spring-acted bolt, having cross-pin looking intorecesses of sash, for the purpose set forth.
